PROBLEM TO BE SOLVED: To provide compression and decompression of data, specifically, a method and device for compressing and decompressing signal data.SOLUTION: There is provided a method for compressing signal data including acquiring the signal data, determining a block length of a plurality of data blocks into which the signal data is divided and determining an exponent of the data blocks; forming a mantissa sequence of the data blocks by using the exponent of the data block so as to compress the signal data included in the data block, and forming compressed data blocks by using the block length, exponent, and mantissa sequence of the data blocks. The method for compressing the signal data increases a compression ratio of the signal data by constructing variable-length data blocks adapted to dynamic features of the signal data. |
